    Abstract: The invention relates to a sensor element, particularly for detecting a physical property of a gas, particularly for detecting the concentration of a gas component, or the temperature, or a solid component or a liquid component of an exhaust gas from an internal combustion engine. The sensor element (20) has a solid electrolyte film (23), for example, and has a first end region and a second end region (202) opposite one another in the longitudinal direction of the sensor element (20). In the first end region, in the interior of the sensor element (20), the sensor element (20) has a functional element, which is electrically connected conductively to a contact surface arranged in the second end region (202) on the outer surface of the sensor element (20). The electrically conductive connection between the functional element and the contact surface has a printed conductor (328) running substantially in the longitudinal direction in the interior of the sensor element (20). The sensor element (20) additionally has a reference gas duct running substantially in the longitudinal direction of the sensor element (20) and communicating via a reference gas opening with a reference gas outside the sensor element (20). The printed conductor (328) and the reference gas duct are arranged such that they at least partially overlap as seen from a top view of the sensor element (20). The invention is characterized in that, at the end of the printed conductor (328) facing away from the end region (201) of the sensor element (20), the printed conductor (328) is angled by an angle (α) of not more than 25°, particularly not more than 14°, relative to the outer side of the sensor element (20). The printed conductor (328) can be composed of a feed line (327) and a collar (329).

    Abstract: The invention relates to a sensor element, in particular for detecting a physical property of a gas, in particular for detecting the concentration of a gas component or the temperature or a solid constituent or a liquid constituent of an exhaust gas of an internal combustion engine. The sensor element (20) has, for example, a solid electrolyte film (21) and has a first end region and a second end region (202) opposite each other in a longitudinal direction of the sensor element. The sensor element (20) has a functional element outside of the second end region (202), in particular in the first end region, which functional element is connected in an electrically conductive manner to a contact surface (43, 44) arranged on the outer surface of the sensor element (20) in the second end region (202). The sensor element is characterized in that the contact surface (43) is rounded, for example with a radius (R), on the side of the contact surface facing away from the first end region (201). The contact surfaces (43, 44) comprise, in particular, three partial regions: head region (432, 442), neck region (433, 443), and torso region (431, 441).
